intercooler installation tips ?

i finished my job for fitting intercooler on top of engine. on the indicated site you will find first and second part of it. scuse me but it is in italian language. bye

I am planing on putting an intercooler on my HJ60T on the intake side of the vehicle with a fan mounted to it. Behind the air cleaner......Thats the plan at this point.

[andrea-PE-ITALY]

what are dimensions of your intercooler? will you use an air fan for cooling of intercooler?

i am currently lookin at grafting a EJ20 Subaru water to air intercooler onto my 3B how ever havin issues finding the space.... i will definately have to go a 2inch body lift to top mount it..as i have stressed all measures to try and make the front mount idea work... i have air cond. and no room up front at all... so im stickin with the top mount idea as the 3B radiator cowling has a far bit of room i will be fabing up a shorter version and mounting the intercooler's radiator in front of the main radiator and with a Spal thermo fan "pulling" the air in with a custom made water sprayer to get the temp down intake air temp down even further...... if anyone can shed some light or ideas my way it wood be great just keep in mind i have a RIGHT HAND DRIVE BJ73 Ihave included a pic of the intercooler im talkin about...... dimension are as follows: 400mm x 230mm x 70mm (inlet pipe hangs below the unit by 75mm) inlet pipe = 51mm OD (2') and the outlet pipe = 71mm OD (3')

Hi.

I had a top mounted water cooled intercooler in my 62 with 12-ht engine.


The engine before install


The cooler it self and mounting hardware


The engine after install


I also added hoodscoop

More pics here http://s44.photobucket.com/albums/f2...ij/intercooler

Now I have a 1990 80 series with 1-htd engine and a front mounted air to air intercooler. I have no pics of the intercooler setup at the moment.

[andrea-PE-ITALY]

nice nice nice. what kind of water pump do you use? how many litres/h ?

[haffi]

I have no idea what brand the pump was or how many liters it pumped, sorry. I dont have that truck any more. so I can´t check for you.

I bought all that stuff used.

But I´m sure this setup worked. I was able to drive uphill in higer gears than before. But I only had the cruiser for about three weeks after the install.

[andrea-PE-ITALY]

never mind, thanks again

anyone got anything new to add to this thred? im keen to see a few set ups

The laws of thermodynamics say that a glycol/air intercooler CANNOT be more efficient because you have more thermal exchanges going on. That being said, a glycol/air intercooler may be better suited for the application because of positioning or the lack of "ram air" for the intercooler.

However of the 2 types I would consider water to air to be better for a diesel application based solely on the speed that 4wd's usually do. Air to air really only starts to work properly just like a radiator does over 70km/hr. In fact they are more efficient the faster you go and quite often you need to go over the speed limit to get the best benefit from them such as over 120km/hr.

Considering some of the fourbying I do like beach work where I rarely ever get over 70km/hr and can be using max throttle and really pushing the 3B hard a water to air would be a lot more efficient for this application.

Here is a pic of PWR water to air intercoolers as mentioned above they use a barrel style setup with separator radiator/pump resevoir etc.



Here's the details on the kits/prices:

Air to air wise top mounts aren't worth it. They get heatsoak in no time. The only benefit is the short IC pipework aiding in good throttle response and less lag. VR4 IC's are good too as already suggested, though my personal preference for used IC's are Nissan GTR good for 300rwkw. Also truck IC's are good and you can get them cut down to suit and are very cheap as well.

I've thought of using a setup like that...

But, I'm kind of leery of an electric water pump to circulate the coolant? Seems like a maintenance item to me?

Any long term prognoses on these in the reliability department? I wouldn't want to be in guatemala and have the thing go out. Of course, you can run without the pump running probably, but still.

If all things are equal, which they are not.

The specific heat of water is 4.1 joule-grams per kelvin. The specific heat of air is 1.0 joule-grams per kelvin.

A 50/50 mix of glycol/water has a specific heat of about 3.5 j-g/k.

So, that means that each cubic cm of glycol water will absorb about 3.5 times as much heat as 1 cubic centimeter of air.

that's why your engine is liquid cooled instead of air cooled. If it were air cooled, the surface area would have to be massive to transfer all that heat to air. But liquid cooling allows much greater heat transfer with a much lower volume of fluid.

Same reason nuclear reactors aren't air cooled, either.

But what are you cooling that liquid with???



































So you still need the air and you've added an extra interface which robs efficiencies! Not to mention that the temperature differences are quite small when compared to coolant and the operating engine which means efficiencies play a larger role.
For low speed use I'd use a liquid/air intercooler but for "on highway" use I'd do my best to use an "air to air" intercooler.

Probably some airflow efficiencies though and less turbo lag as well.

Who are Joule Gram and this Kelvin guy and what do they have to do with this thread... and who is putting a liquid cooled nuclear reactor in a cruiser? Really as if the LC's weren't heavy enough, not to mention the fact that our trails are closing due to abuse- a spill of radioactive waste out on the trail via a LANDCRUISER..... That is all we need. Shoot, now they're gonna shut this website down if thread gets any tech on that issue.!!!

My setup.

OK, so with a liquid to air cooler-reguardless of efficiency- what happens when the unit springs a leak?
